Fish the fly deep, using split-shot and an indicator.
Dead drift is the best technique. Make sure to mend you line.
I like to fish it in broken or fast water,
 but it will also work in slow moving current.

It immitates the caddis pupa or Mayfly emerging,
 but who cares as long as the fish hits it.

I have had success with this pattern everywhere
 I have used it.
It is a "go to" pattern for me.

My clients and fishing friends have also found that
 it is the one pattern they can count 
to get stricks, when other flies are not working.

I use:
 Any brand scud/shrimp/caddis hook, but I perfer
 Targus shrimp/scud/caddis hooks

Size's 14 - 20

BWO  Ultra-Fine dubbing by Universal Vice
Red thread, any brand, but  I use 
Uni-thread 6/ot
Closed-cell foam in white.

Tie on the white foam to create the gas bubble or
 wing caseing.
start at the middle of hook and go forward toward 
the eye, tie it down, 
and bring it back towards the middle and ty it off. 
Start at the eye and dub thread thin with BWO
 dubbing and figure-eight around the foam, from
 below the foam and wrap back to the curve of the 
hook. then come back up the length of the hook
 with the thread, only , to create the rib.
 Tie it off.

DONE
